Natalie Dormer will join the cast of Mockingjay Parts 1 and 2: The Hunger Games' final chapter that will be split into two films à la Harry Potter, Twilight, etc. The 31 year-old British actress, known for her roles as Margaery Tyrell in HBO's Game of Thrones and Anne Boleyn in Showtime's The Tudors, will play Cressida, the resident director in the capitol who joins the districts' revolt, Lionsgate have announced.

Cressida's camera crew is charged by Plutarch Heavensbee (Philip Seymour Hoffman) with documenting Jennifer Lawrence's character Katniss Everdeen's activities in the rebellion against the powers that be in order to create propaganda to boost rebel morale. According to E!, Dormer is the first actor announced to join the franchise who has not starred in The Hunger Games or its upcoming sequel, Catching Fire, though appareantly Julianne Moore is currently in talks to play the ruthless rebellion leader and president of District 13, Alma Coin.

However, the Reading-born actress with her trademark curly blonde locks will have to have a bit of an image change to play the tough Cressida: she is described by the author in the books as having a shaved head and green vine tattoos, so many hours in the make-up chair await for Dormer.

Though Dormer has excelled herself in roles on television, including Game of Thrones, The Tudors, and Elementary, she has also appeared in a few strong movies too, meaning it's high time she started appearing in some real blockbusters. You may recognise her from Casanova, Captain America: The First Avenger, and will be seen appearing in Ridley Scott's The Counselor this year alongside Michael Fassbender.
